VISE

SPECIFICATION forming part of Letters Patent N 0. 686,304, dated November 12, 1901. Application filed February 11, 1901. Serla1No.46,874. (No model.)

To all whom it may concern:

Be it knownthatl, CARLOS N. GRACE, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsyl vania, have invented certain new and useful Improvements in Vises; and I do declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to Vises.

The object of thelinvention is to provide a vise capable of adjustment from a horizontal to a vertical position, and vice versa, and thereby adapting it to various kinds of work, some of which may be more conveniently handled when the vise is in a horizontal position and some of which may be more conveniently handled when the vise is in a vertical position.

With this and other minor objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, which will be hereinafter more fully described, and particularly point-- ed out in the appended claim.

In the accompanying drawings, Figure 1 is a side view of my improved vise, showing it supported at the end or side of the bench, the full lines representing it in a horizontal position and the dotted lines representing it in a vertical position. Fig. 2 is a longitudinal sectional view. Fig. 3 is a transverse sectional view. Fig. 4 is a top plan view showing one of the jaws adjusted to bring its clamping-face at an angle to its cooperating jaw for tapered work.

Referring now more particularly to the drawings, the numeral 1 denotes the frame of the vise, comprising the side pieces 2, having inwardly-projecting flanges 2, bolted to the flat base 3, which base is seated upon a disk 4, secured to the end or edge of the table or bench 5. A bolt 6 extends through the table, the disk 4, and flat base 3 and is provided with a hand-nut 7, by means of which the base is clamped to the table in desired adj ustment.

9 denotes a bearing which is in the form of a box and is provided at its forward end with trunnions 10, which project through apertures 11 in the parallel side pieces of the frame and secured therein by washers and screws 12 and 13, respectively. This bearing or box has uponfits upper side at its rear end a transverse ledge 14, the forward face of which is curved in the arc of a circle and is provided with a curved recess 15. The upper side of this bearing or box is provided with a boss 16, which receives a seat 19 in the base 20 of a jaw 21, which is held in place by a screw 22, passing through said jaw into the boss. The base of the jaw is provided with a curved lip 23, which projects into the curved recess of the transverse ledge. A pin 24 is inserted through the base of the jaw and into the upper side of the box orbearing to hold the face of the jaw in parallelism with the face of its cooperating jaw.

25 denotes the sliding jaw, which is provided with a shank 26,which projects through the box or bearing and is formed with a longitudinal groove 27 in its base. 29 projects upwardly from the inner wall of the box or hearing into the groove, and a feed-screw 30 extends through the holes in the ends of the shank through the nut and is located in the groove of the shank and is provided with squared'ends by means of which it may be rotated to slide the shank with its jaw toward or away from the other jaw.

31 and 32 denote holes formed in one of the side pieces, and 33 denotes a hole formed in the side of the bearing or box.

34 denotes a pin.

When it is desired to hold the jaws of the vise in the position shown in full lines in Fig. 1, the pin 34 is inserted through the hole 32 in the side piece of the frame and into the hole 33 of the box or bearing. The work may now be grasped and held between the two jaws by properly adjusting the feed-screw. If it be desired to change the position of. the jaws so that they will occupy a vertical plane, the pin is withdrawn from the apertures and the box swung into the position shown in dotted lines in Fig. 1. The pin is now inserted in the hole 31 of the side piece and the hole 33 of the box or bearing, thus holding the vise with its jaws in a vertical position. When in this position, heavy work may be more readily engaged with the Vise, as it is only necessary to lift it upon the lowermost jaw, and this may be done by one person, who after the work has been lifted upon the lowermost jaw may operate the feed-screw to draw the two jaws together. This device, it will therefore be seen, is a labor-saving one and by its employment work may be more expeditiously done.

From the foregoing description, taken in connection with the accompanying drawings, the construction and mode of operation of my improved vise may be readily understood without requiring a more extended explanation.

Various changes in the form, proportion,

and minor details of construction may be made Within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

In a vise, the combination with a supporting-frame having inwardly-projecting flanges and parallel side pieces, of a box or bearing journaled between the side pieces and carrying coacting jaws, a plate secured to the under side of the supporting-frame, a second plate adapted to be screwed to abench or table, and a bolt extending through the frame and plates and provided with a clampingnut, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

CARLOS N. GRACE.
